I'm yet to figure out why common core is so terrible?
But NCLB basically set up the worst performing schools (compounded by terrible social problems) for failure.
CC is a different brand of crap. It assumes kids in Texas learn the same as in New York, and creates this soulless, almost industrially manufactured youth to provide "services." It doesn't teach kids HOW to think, it teaches them WHAT to think.
It's no more logical to assume all kids in Texas learn the same way than that all kids in the entire country learn the same way.
"Them New York kids is differ'nt! Down here, our kids like real 'Murican stuff like gun-shootin' and truck-drivin' and baby-makin' after football games! They don't need no humanistic education or postmodern literary criticism! Yee haw! Pew pew pew!"
